Retractable crane built into hybrid trailer load bed

Abstract

A hybrid trailer with a built in retractable hydraulic crane to handle different configurations of platform surface bodies. It will raise the platform surface body vertically away from the chassis frame placing the platform surface body in the desired location. Two telescoping arms extend out to lift and retract into a recessed area in the bed of the trailer for storage. It is operated by remote voice control. A solar collector enables operation in remote locations and use of the crane for external lifting operations.

What is claimed is: 
     
       1. A retractable crane apparatus built into a bed of a trailer, the crane apparatus comprising:
 a trailer bed comprising a bed for receiving loads thereon and a recessed storage area in the bed; 
 a hydraulic base mounted on a forward end of the trailer to provide the hydraulic power for a crane apparatus; 
 a boom assembly pivotally attached to the hydraulic base to extend outwardly from the base at variable distances and angles; 
 a crown chapiter on an outer end of the boom assembly to house the controls for the crane apparatus; 
 a pair of lift arms pivotally attached to the crown chapiter for lifting load bodies onto and off of the trailer bed and for general use as a crane, the lift arms, crown chapiter, and boom assembly extending upwardly and outwardly from said trailer bed for lifting loads and alternately retracting down below the upper surface of the bed for storage in the recessed storage area in the bed; 
 a remote control for wireless communication with the controls for the crane apparatus to operate the crane apparatus; and 
 an electric power source for powering the crane apparatus. 
 
     
     
       2. The crane apparatus of  claim 1  wherein the electric power source comprises a plurality of solar energy panels mounted on the trailer for powering the crane apparatus. 
     
     
       3. The crane apparatus of  claim 1  wherein the remote control comprises a voice activated remote control device. 
     
     
       4. The crane apparatus of  claim 1  wherein the boom assembly comprises a plurality of pivotally connected elements forming a boom hydraulic extension which extends out and retracts itself. 
     
     
       5. The crane apparatus of  claim 4  wherein the boom assembly is fabricated from at least one of light aluminum steel, flex steel, and hardenable steel. 
     
     
       6. The crane apparatus of  claim 1  wherein the lift arms comprise two hydraulic sections attached by a pivot each resembling an arm having a hand pivotally attached on an outer end of the arm. 
     
     
       7. The crane apparatus of  claim 1  further comprising:
 a chassis frame supportively connected to one or more of said load bodies; 
 at least two axles mounted to said chassis frame and a plurality of air ride bags between each axle; 
 wherein said chassis frame includes spring suspension for rolling support; and 
 adjustable portable leg arms attached at each corner of the chassis frame.
